We are now sure that Rose Quartz didn't shatter Pink Diamond, so who did this? Today I offer you my own theory which seems quite credible.

My Theory

Pearl is the Pink Diamond's Pearl

Every Gem has a colored diamond on her chest in order to indicate her belonging. For example, Peridot and the five Rubies have a yellow diamond because they work (or worked) for... Yellow Diamond. When she wears her space suit, Pearl has a pink diamond, so it seems logical that she worked for Pink Diamond.

In the episode 4.12 ("Adventures in Light Distortion"), Pearl says "When I still served... (short silence with her eyes lowering) ...Homeworld, I saw it myself." That means that Pearl has a secret role she wants to hide, and she went to the Zoo, property of Pink Diamond. All these proofs obviously demonstrate that Pearl is in fact the Pink Diamond's Pearl.

The murder of Pink Diamond

Who murdered Pink Diamond ? We learn evidence that Pearl is guilty of Pink Diamond's murder, especially in episode 5.2 ("The Trial").

<p data-parsoid="{"dsr":[1209,1392,0,0]}">1) Blue and Yellow Diamonds loved Pink Diamond. It is obvious that Blue Diamond was in love with Pink Diamond, and Yellow Diamond loved her too (4.15 "That Will Be All"). During her song, Yellow Diamond reveals her feelings. She is not completely stern and stoic: Yellow is very kind with the other Diamonds.

<p data-parsoid="{"dsr":[1209,1392,0,0]}">2) The murder of Pink Diamond was a win for the Crystal Gems only. Pink Diamond was the leader of the Earth's colonisation. The only winners of her murder are the Crystal Gems, because it had a huge impact on the invasion. However, Rose Quartz is full of love for all creatures, and she couldn't kill anybody, even if they were her enemies ("Bismuth"). It is not the case with Pearl, a quite aggressive Gem ready to do anything for her beliefs and to help Rose. And by killing a Diamond, Rose could become a legend of the rebellion.<p data-parsoid="{"dsr":[1209,1392,0,0]}">3) Pink Diamond was killed by someone close. In "The Trial", Steven's lawyer explains that nobody gave the alert for the arrival of Rose Quartz, but she was already known as a rebel. The lawyer insists on the role of Pink Diamond's Pearl which was supposed to be just next to her mistress. She has the best opportunity to kill her quickly, and then accuse the perfect scapegoat: the leader of the rebellion Rose Quartz, as fast and discreet as a ghost (or a ninja, if you prefer this comparison).

4) Pink Diamond was shattered with a sword ("The Trial"). However, Rose's sword cannot shatter any Gem (3.20-21 "Bismuth"). Yellow Diamond didn't need any weapon (she threw lightning bolts during "The Trial"). But who, except Rose, uses a sword? ...Pearl, obviously.

5) The murder was thousands of years ago. When Pink Diamond died, "Rose Quartz had been a recognized threat for several hundred years" (Steven's lawyer in "The Trial"), so it was at the very beginning of the rebellion. Indeed, the Crystal Gems have existed for more than 5750 years (date when Garnet joined them, according to the episode 2.22 "The Answer"). We can suppose that just after this murder, Pearl joined Rose Quartz in her rebellion.


Pearl's ultimate betrayal

Image 36
This is what happened, from my point of view :<p data-parsoid="{"dsr":[1683,2012,0,0]}">One day, Pearl met Rose Quartz (maybe she just saw her during one of her attacks) and she fell in love. She realized that Rose's goal was fair, so she decided to do something...

Pearl is quite an unstable person, very troubled by her feelings. She passes from joy to anger (to sadness) very quickly, and she sometimes seems to act without reason, especially when she follows her heart (for example, episode 4.6 "Last One Out of Beach City"). This time, she crossed the line. She killed Pink Diamond in her palanquin and then accused Rose Quartz. It was both a way of escaping death and a "gift" offer to Rose. It could also be a manner to rise with Rose as the powerful renegade who killed a Diamond, and attract some other Gems in the rebellion.

In S5E6 “Gemcation”, Pearl fears that Steven has seen something upsetting on Homeworld, and it sounds as if she is about to confess a long-hidden secret about the Diamonds starting with “I”. She could be saying “I know what really happened,” but I feel it is far more likely that she may be saying “I shattered Pink Diamond.”</p>


To conclude, after accusing Rose Quartz and Yellow Diamond, Pearl is a good alternative to the role of the murderer. It would be a revelation which is both shocking and satisfying for the narrative. (If you want to know my other theory, read why I think that White Diamond is Homeworld)

Confirmed Theory

In "A Single Pale Rose", Rose Quartz was actually Pink Diamond and that Pearl helped Pink Diamond fake her shattering to end Gem invasion of Earth. Pink Diamond gave Pearl a promise for thousands of years to not talk about her faking her shattering.
